During Google’s financial call today, which we have full coverage of in our liveblog, CEO Larry Page revealed that Google’s run rate for mobile is now at $8 billion. That is quite the increase from the $2.5 billion it announced last year:

This time last year I announced that our run-rate for mobile advertising hit $2.5 billion. That seemed like a pretty big number — even for Google. Now we have built up additional mobile revenue from users paying for content and apps in Google Play. Including these new sources grossed up, I can announce our new run-rate for mobile is now over $8 billion. That’s quite a business

However, CFO Patrick Pichette added that its run rate for the quarter also included ads and Google Play content revenue. Not surprisingly, the company noted the majority of that $8 billion figure comes mostly from ads. During the call, Page also confirmed there are still roughly 1.3 million Android activations daily: expand full story

Like us, Google appears to be confused by last night’s report—where AT&T’s CEO Randall Stephenson told a questioner that the fault of Android smartphones not receiving updates is Google’s.

Stephenson blamed Google, claiming, “Google determines what platform gets the newest releases and when. A lot of times, that’s a negotiated arrangement and that’s something we work at hard. We know that’s important to our customers. That’s kind of an ambiguous answer because I can’t give you a direct answer in this setting.”

Google refuted that point of view tonight, telling us:

“Mr. Stephenson’s carefully worded quote caught our attention and frankly we don’t understand what he is referring to. Google does not have any agreements in place that require a negotiation before a handset launches. Google has always made the latest release of Android available as open source at source.android.comas soon as the first device based on it has launched. This way, we know the software runs error-free on hardware that has been accepted and approved by manufacturers, operators and regulatory agencies such as the FCC. We then release it to the world.”
